This device contains protection circuitry to protect the inputs against damage due to high static voltages or electric fields. However, it is advised
that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high–impedance circuit. A
destructive high current mode may occur if V
in
and V
out
are not constrained to the range V
SS
Due to the sourcing capability of this circuit, damage can occur to the device if V
DD
is applied, and the outputs are shorted to V
SS
and are at a
logical 1 (See Maximum Ratings).
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either V
SS
or V
DD
).

or V
out
